Double ceil double x.
Floor int c.
Returns the largest integer that is smaller than or equal to x i e.
Long double ceil long double x.
In a c program unless you re using the tgmath h macro to call this function floor always takes and returns.
The largest representable floating point values are exact integers in all standard floating point formats so this function never overflows on its own.
Double floor double x.
Otherwise if arg has integer type or the type double floor is called.
Rounds downs the nearest integer.
Include math h applies to.
In the c language the required header for the floor function is.
C allows overloading so you can call overloads of floor that take and return float and long double values.
The floor function returns the largest possible integer value which is equal to the value or smaller than that.
If arg has type long double floorl is called.
Float ceil float x.
Long double floor long double x.
It takes single value whoes floor value is to be calculated.
Float floor float x.
Additional overloads for integral types.
In mathematics and computer science the floor and ceiling functions map a real number to the greatest preceding or the least succeeding integer respectively.
This function is also declared in cmath header file in c language.
However the result may overflow any integer type including std intmax t when stored in an integer variable.
1 3 computes the largest integer value not greater than arg.
Here x is the floating point value.
For information and restrictions about using the sse2 implementation see set sse2 enable.
C floor the floor function in c returns the largest possible integer value which is less than or equal to the given argument.
Floor has an implementation that uses streaming simd extensions 2 sse2.
Double ceil t x.
